1.8mm LEDs (25)
Pack of 25
- Red, Yellow, Green, Orange and Purple LED's works on 1.8 to 2 volts
- White and Blue need 3 to 3.5 volts for proper operation
- All 1.8mm LED's operate on 20ma, a current limiting resistor should be used when lighting LED's in most applications. To find the correct resistor subtract led working voltage from your source voltage then divide by .02 use a resistor equal to that amount or greater, do not use a smaller resistor.
